#OpGlobalBlackout - Should you be worried?

Will the hacker group Anonymous make good on its threat to take down the Internet Saturday? Probably not. But it could slow it down, according to a number of security experts. And it may depend in part on how unified Anonymous is about the attack -- there are some indications of divisions within the group.

Anonymous has threatened retaliation for the arrests of about 25 of its members last month, and is also focused on what its members believe is a continuing threat by Congress to censor the Internet through revised versions of the Stop Internet Piracy Act (SOPA) and the companion Senate bill called the Protect IP Act (PIPA), even though the legislation was put on hold in January.

And it is essentially daring anyone to stop Operation Global Blackout -- the group announced March 31 as the date of the attack, along with the method they intend to use -- disabling the Domain Name Service through distributed denial of service attacks on the root servers of the DNS with an attack tool called "ramp," which stands for "reflective amplification." While two of the basic rules of hacking are: Don't tell your target in advance and don't give away your methods, Radware security vice president Carl Herberger says the announcement is a classic Anonymous tactic.
